Charlie Sheen has returned to work on Two and a Half Men.
Sheen's and the show's reps said he arrived on the set Tuesday morning to begin production on his hit CBS sitcom's final four episodes of the season.
Charlie Sheen entering rehab
Production on the show — TV's top-rated comedy — was suspended three weeks ago when the actor announced he was entering rehab as a "preventive measure." The nature and location of his treatment remain unknown.
Sheen's time off did not greatly affect Men's production schedule, as CBS already had three episodes in the can at the time of his announcement, along with a previously scheduled week off in March. The network ordered 24 episodes of Men this season.
